In 1989 , emergency responders received a 9-1-1 call from Maria Rossi confessing that she had killed three people. Upon arrival to the Rossi home, police investigators also found Mrs.Rossi at the scene in shock and covered in blood. She was arrested and charged in the murders.
In 1991, Rossi was found not guiltry by reason of insanity and remanded to the South Hartford State Asylum. Later that year she was transferred to the Centrino Mental Hospital for the criminally insane in Rome , Italy.
Maria Rossi's daughter, Isabella,believed that the killing were commited after her mother flew into a psychotic rage. Nearly twenty years later, Isabella was told an exsorcism was being conducted on her mother at the time of the murders.
In order to gain insight into of the spiritual plight that her mother endured and to better understand the truth about what happeded that night , young Rossi traveled to Italy.She enlisted the help of a documentary filmmaker, Michael Schaefer , to join in her quest to determine if her mother is mentally ill or demonically possessed.
Once in vatican City , Isabella met two young exorcists, Father Ben Rawling and Father David Keane,MD. They offered to help her mother using unconventional methods combinning both science and religion. Isabella and her crew attended a series of unsanctioned exorcims that became increasingly terrifying.
